[Octave-bug-tracker] [bug #30715] imread fails to read uint16 tif image

[Jonathan Thomson]

Follow-up Comment #10, bug #30715 (project octave):

The QuantumDepth is defined in the header magick/magick_config.h so the
QuantumDepth can be easily given to __magick_read__.cc simply by including
that header.

Unfortunately images with bit depths higher than the QuantumDepth are still
being incorrectly read or throwing an error even with the #if (QuantumDepth >
?) statements added because gm is incorrectly reporting the images bit depth,
so case 8: is always run. From the post linked to below it sounds like
min(depth,QuantumDepth) is returned from gm, but from the documentation
modulusDepth() should be returning the image's depth. It's confusing. My
investigation is on going.
